Many factors determine the outcome in NASCAR races including car design and mechanics, the weather, and the efficiency of the pit crew . A recent study suggests that for NASCAR racers, starting position is strongly related to finishing position. A random sample of NASCAR racers was obtained, and the average starting position (x) and average finish position (y) for the 2018 season were recorded.
